In Brazilian Portuguese, 'arco' is the standard term for architectural arches and is used in historical contexts when discussing colonial buildings. In American English, 'arch' is also used metaphorically to describe someone's manner or demeanor (e.g., 'arch behavior'), which translates to 'comportamento travesso' or 'atitude marota' in Brazilian Portuguese. The arch of the foot is important in Brazilian culture due to the popularity of capoeira and other physical activities.
